CAP FOR SHEET-METAL PAINT-CANS.

SPECIFICATION forming part of Letters Patent No. 323,623, dated August}, 1885.

Application filed June 22, 1885.

To all whom it may concern:

Be it known that I, EDMUND K. BAKER, a citizen of the United States, residing at Springfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in (laps for Sheet-Metal PaintCans, of which the following is aspecification.

This invention relates to improvements in sheet-metal cans, the object being to provide for cans which are adapted to hold paint and similar substances, and which have through one end an opening for inserting and removing the contents of the can, an improved device for closing said openinghermetically and for indicating the color of the contents of the can.

In the drawings forming part of this specification, Figure 1 is a sectional view of the end and a portion of the sides of atin or sheet-metal can, and Fig. 2 is a view in transverse section of a device for closing the opening in the end of the can, Fig. 1, cmbodying my improvements. Fig. 3 is a plan view and a sectional edge projection of the base-plate of said closing device. Fig. 4. illus tratcs a glass dish, and Fig. 5 is a plan view of the perforated top plate of the closing device.

In the drawings, 0 0 indicate the sides of a metal can, and a the top thereof, having a depressed central portion, b, and through the latter a circular opening, a shoulder, a, being formed around said opening, said shoulder being sunk below the general level of the top of the can a distance about equal to the thickness of the closing device, hereinafter described. The ahovereferrcdto opening 2: is of suitable diameter to admit of filling the can therethrough with paint or similar substance.

The cap or closing device for the opening 2: in the end of the can consists of three parlsviz., the baseplatc c, the glass disk 11, and the perforated top plate, 0-all united, as hereinafter set forth, to form the complete cap or closing device for the can, a sectional view of which is shown in Fig. 2.

lilctal cans of this class, which are used for putting up paint in, are often provided with some means for indicating on the out. side thereof the color or quality of the contents; and, as above mentioned, one object (Xe model.)

of this invention is to provide improved means of said indication, and to this end said cap or closing device is constructed and applied to the can as follows: The base-plate c is first made in the form shown in Fig. 3, that is to say, with a depressed central portion, r, and an upwardly-turned border, .58, and the surface of said plate within said depressed part is then coated with paint, (I, of the color and quality of that with which the can is tilled, and for whose cap it is to serve as a part. Said paint having been applied to the base-plate, the glass disk It is placed over the painted surface thereof, and the perforated top plate, 0, so formed, as shown in Fig. 2, that its inner edge bears on the glass It and holds it down with more or less spring force, is then placed on plate 0, and then the border m of the latter is bent inward upon the plate 0, firmly locking said two plates and the glass dish together, as shown in Fig. 2.

"The diameter of the cap or closing device just described is such that it fits in the aforesaid depression I) in the end of the can so that the upper side of the top plate, 0, is about in the same plane as the end a of the can, and the latter having been filled with paint, as aforesaid, said cap is soldered around its border to the can, hermetically closing the orifice s, but showing through the glass It the coat of paint (I of like color to that in the can, as above described. Thus said cap is f0rmed,e1nbracing the base-plate 0, having the coat (I of paint on its inner depressed surface part, the clear glass disk 71?, through which can be seen the coating d on the base plate, and the top plate, 0, all secured to gether, as above described.

\Vhat I claim as my invention is- A compound cap for closing the orifice in sheet-metal paint-cans, consisting of the centrally-depressed circular metallic base-plate 0, having the upturned border 0, and having applied to said depressed portion a coat, (Z, of paint, the perforated metallic top plate, 0, fitting within the border at, of plate 0, and the clear glass disk h,iuterposed between said two plates, all combined and united substantially as set forth.
